(ON SLIDE # 7)
1. GCS900 GRADE CONTROL SYSTEM OVERVIEW: (50 Mins)
a. GCS900 is a system designed to aid the operator in an
array of construction and grading operation. The system
provides both vertical or vertical and horizontal
instruction of where the blade needs to go to be at grade.
This can be displayed as directional lights for manual
adjustments to be made by the operator. Or it can also be
sent to a hydraulic valve to move the blade automatically.
(ON SLIDE # 8)
b. The utilization of grade control can improve
production by increasing the accuracy; thus minimizing the
number of passes required to get to grade; also reducing
fuel consumption and machine wear.
c. The system gives the operator the ability to run the
machine in manual assist or auto blade control, while
5
monitoring project design progress on the control box in
front of them. Grade Control System is just as effective in
either day or night operations.
(ON SLIDE # 9)
d. There are many different grade control applications
such as Runway/Taxiways, Aircraft parking aprons, Landing
zones, HLZ’s, Road and route missions, Building pads,
Vehicle parking lots and facilities, General grading and
drainage.
(ON SLIDE # 10)
e. The GCS900 is designed for the Marine Corp’s 120M
grader and 850JR MCT dozer. The 120M is capable of slope
only, sonic, laser and GPS operations. The MCT is only ca-
pable of laser and GPS operations.
(ON SLIDE # 11)
f. The GCS900 uses electronic components such as
rotation, slope, sonic, laser and GPS sensors to provide
accurate blade positioning and automatic blade control.
These sensors need to be calibrated by the operator in
order to be accurate.
(1) Rotation, slope, and sonic sensors: These sensors
all work together measuring each component separately
and using algorithms to calculate the exact blade
location.
(a) Rotation Sensor: The rotation sensor is
mounted to the circle components for the blade of the 120M.
There is no rotation sensor on the MCT. This sensor
measures the rotation angle of the blade, allowing the
operator full function of rotating the blade while
operating.
(b) Slope Sensor: The slope sensor measures the
slope of a component on the tractor. The same sensor can be
mounted to various components. It has arrows on it which
indicate the direction of the measurement. The 120M
utilizes three of these sensors. One will be mounted to the
mainframe of the tractor which measures the main fall
slope. Another sensor is mounted to the circle of the blade
which measures the slope of the blade. The third slope
sensor is added to the blade itself on a bracket between
the mast bracket and riser. This sensor measure blade
6
pitch/roll, which allows the operator more control of his
blade while operating. The MCT only uses one sensor to
measure the slope of the blade while operating.
(c) Sonic Tracer: The sonic tracer sensor is used
to provide elevation control. The system is designed for
use on motor graders for tracing string line, curbs and
previous pass. It also has lights that indicate whether the
blade is on or off grade. This sensor allows the operator
to easily extend an existing surface, cut or fill to
desired depths, or create new surfaces with more consistent
slopes for drainage.
(2) Laser: Consist of the GL722 laser transmitter,
machine laser receiver and rod receiver.
(a) The GL722 projects a level or sloping plane of
laser light above the job site area. Using a laser receiver
mounted to the blade the operator can grade the surface to
match level or sloping plane.
(b) The machine laser receiver guides the operator
on grade by providing adjustment either up or down. This
receiver can be used manually, but with low accuracy. It is
also utilized automatically which allows the tractor to
adjust the blade for the operator keeping the laser in the
middle of the receivers range improving accuracy.
(c) The rod receiver allows the operator or a
supervisor to check the accuracy of the machine on a job
site. The laser and receiver can be as accurate as 1/16 of
an inch or about the width of a pen tip. This receiver can
also be used to plan and estimate a jobsite by measuring
cuts and fills. The grade rod reads in tenths of a foot
commonly known as survey feet. To help better understand
this type of measurement, know that by dividing 12 inches
by 10 tenths equals 1.2 inches per tenth. Example: 3 tenths
of a foot equals 3.6 inches.
(3) Global Positioning Sensors (GPS): Consist of base
station/radio and machine receiver/radio. The system uses
more than 50 satellites orbiting in space to calculate the
machine vertical and horizontal location on earth.
(a) The base station, receiver and radio, is set
up over a hub. A hub is a point with known location such as
northing, easting, and elevation. Setting up the base
station over a known hub allows for more consistent work
for multiple day projects. The radio is used to communicate
to the machine radio for more accurate positioning of the
7
machine. The accuracy for the GPS is one tenth of a foot.
This is equivalent to the width of a golf ball. Most
vehicle and hand held GPS devices, including cell phones,
are only accurate to within 32 feet.
(b) The machine receiver and radio are used to
calculate the position of the machine by receiving its own
GPS coordinates and relaying them back to the base station
for corrections.
(ON SLIDE # 12)
(4) Using the on board control box the operator can
create common designs such as HLZ, runways, pads and V-
ditches. If a mission requires, this allows the operator to
construct projects without the external help of surveyors.
The GCS-900 can be used manually by the operator following
the guidance of the provided adjustment lights. Or, the
operator can select automatic mode which allows the tractor
to control horizontal movement of the blade. When time
permits or a complicated design needs to be created by
surveyors, the design can be loaded into the control box.
This allows for the construction of complex designs such as
roads with multiple turns and slopes and even one design
with multiple pads or sites.
(ON SLIDE # 13)
2. How it Works: Historically, the first laser system was
developed and implemented into the construction world in
1965. The conventional method required numerous stakes and
man hours to prepare a work site. Unavoidably resulting in
a congested construction site. By utilizing the grade con-
trol system all the congestion is eliminated, by the use of
the onboard control box. The control box displays the pro-
jected target instate with the guidance to go from current
grade to projected grade.
(ON SLIDE # 14)
(a) “Slope only” refers to the three sensors on the
machine that calculate the actual position of the blade.
The operator can input the desired cross slope into the
control box. Once the input is loaded the control box cal-
culates the difference from the operator input and the ac-
tual position of the blade. From there corrections are sent
to the hydraulic valve to move the blade to the correct po-
sition, in order to achieve the desired grade slope.
8
(ON SLIDE # 15)
The slope and sonic sensor: Conventionally, one way to do
what the sonic tracer does, is to run a string between two
points and mark with grade stakes the cuts and fills. (ON
SLIDE # 17) The sonic tracer was introduced later in the
mid 1980’s. This allowed the operator to extend an existing
surface and cut/fill more accurately and faster. This saves
both time and money.
(ON SLIDE # 16)
(b) “Sonic tracer” is positioned over a reference
such as a curb or string-line.
(ON SLIDE # 19)
The operator then presses the reset (bench) on the
control box. A sound wave then travels down to the
target and back to the tracer. The tracer now knows
its distance from the target based on the amount of
time sound waves took to reflect back; and then
maintains this distance from the target until it is
reset.
(ON SLIDE # 17-21)
(c) Laser System:
(1) A laser beam is shaped using optics to hold a
small diameter spot over distances. The laser beam
is then rotated at 600 RPM which creates 360 degree
plane of light above the work site. The laser beam
must then strike the center of the laser receiver
for the blade to be on grade. If the beam strikes
high or low the blade will automatically raise or
lower to get on grade.
(ON SLIDE # 22)
(d) GPS Grade control (3D): In 1999 the first designs
for GPS guidance where being introduced. (ON SLIDE # 26)
Before GPS was introduced surveyors relied on, and still
utilize, robotics to survey an area. This technology was
introduced for machine control but GPS proved more ad-
vantages to a wider variety of projects. The conventional
method of robotics only allows for one machine to be con-
trolled by one total station.
9
(ON SLIDE # 23)
GPS grade control method allows for multiple tractors to
work simultaneously to together on a project. These trac-
tors can even be working at different elevations from rough
cutting/filling with a scraper or dozer to final passes on
grade with a grader or compactor.
(ON SLIDE # 24)
(a) The system uses more than 50 satellites orbiting in space to calculate the vertical and horizontal location
of the blade within +/-.1’.
(ON SLIDE # 25)
(b) A DTM or digital terrain model is designed on a computer and then uploaded to the control box.
(ON SLIDE #26)
The DTM is designed by surveyors for multiple slope pro-
jects. This design can be loaded into multiple tractors and
each tractor can work on the project at the same time.
(ON SLIDE # 27-29)
(c) The GPS receiver calculates where you are on earth.
(d) The control box determines the difference be-tween where you are (using GPS coordinates) and where you
want to be on the project design (DTM).
(e) A signal is sent to the hydraulic valves to move the blade to match the project design.
(ON SLIDE # 30)
(e) Field Reference guide: Is an operators quick
reference tool designed to assist the operator in the
field. It provides a check list for all critical task which
are required to get the system up and running. The field
reference guide is continually updated; therefore the
operator should ensure that he has the latest available
version. Currently the Marine Corps has both Version V11
and V12.
10
INSTRUCTOR NOTE:
Have the students get out their filed reference guide and
go over it briefly with them.
(ON SLIDE # 31)
(f) CB430 Control Box: Is a the machines on board
computer, which consist of a display and keyboard in
one box, and is mounted in front of the operators
chair. The system is used to configure, calibrate and
operate the system. It has the ability to store and
transfer information about multiple machines. The
operator has the ability to design projects on the
screen and it displays the blade and machine positions
in real-time in relation to the designed project.

3. Slope Only and sonic Operation: (20 MIN)
1. Grade Control System Slope Only: The AS400 Slope
Sensor is mounted on the circle behind the blade, and
measures the slope across the blade. The Rotation Sensor is
mounted on the turn table and measures the rotation of the
blade from perpendicular. The Main-fall Sensor is mounted
on the goose neck and measures the slope of the machine in
the direction of travel. The three sensors on the machine
calculates the actual position of the blade on the project.
The operator inputs the design cross slope into the control
box. The operator then controls the elevation on one side
(typically the toe). The control box then calculates the
difference from the design slope and actual slope of the
blade. Corrections are sent to the hydraulic valve to
automatically move the blade to the design slope.
(ON SLIDE # 67-68)
Slope-Only Components in the Machine: Slope only
operation is (Referenced in the field Reference Guide).
Operator in puts the slope of the project, then selects
which side of the blade will be controlled by the slope
sensor.
37
(ON SLIDE # 69)
2.CB430 Sonic Tracer: Sonics are used in conjunction
with slope control for dual control. This allows the grader
to trace an existing surface, such as a runway or fixed pad
to extend the surface.
a. Sonic Components and Operations: The Sonic tracer
is positioned over a surface to trace string line, curb,
existing hard ball, ect. The operator lowers the cutting
edge to the desired elevation and presses the reset on the
Control Box. A sound wave travel down to the target and
back to the tracer, the tracer now knows the distance from
the target based on the amount of time the sound wave took
to reflect back. The Tracer will maintain this distance
from the target until it is reset by the operator.
b.Slope only: Slope only allows the operator to enter
a cross slope value into the control box to automatically
control one side of the grader blade.
